8 Claims. (01. 216-25) The present invention relates to new and useful improvements in stamp aflixing machines and more particularly to a hand operated machine.

An important object of the invention is to provide a plunger operated carriage on which a roll of stamps is supported together with mechanisms for feeding the stamps in a step by step movement to a cutter which is synchronized with the feeding of the stamps and providing a moistening roller mounted for swinging movement under the carriage to fold the stamps under a presser plate and simultaneously moisten the underside of the stamps as the carriage is moved downwardly into its stamp afiixing position.

A further object of the invention is to provide a stamp aflixing machine of this character of simple and practical construction, which is eflicient and reliable in operation, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer tolike parts throughout, and in which:

Figure 1 is a side elevational View;

Figure 2 is a view in elevation showing one of the open sides of the frame;

Figure 3 is a similar view of an opposite side of the frame; v

Figure 4 is a vertical sectional view taken substantially on a line 4-4 of Figure 3;

Figure 5 is a similar view showing the completion of the downward stamp affixing movement of the carriage;

Figure 6 is a fragmentary vertical sectional view taken substantially on a line 6-6 of Figure 2; v

Figure 7 is a tranverse sectional view taken on a line of Figure 4 and showing the cutter;

' v Figure 8 is a vertical sectional view taken on a line 8-8 of Figure 2, and

Figure 9 is an enlarged fragmentary vertical sectional view taken on a line 9-9 of Figure 2 and showing the guide channel for the cutter actuating slide.

Referring now to the drawings in detail wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention the numeral 5 designates an inverted U-shaped stationary frame having an opening 6 in its top in which a plunger 1 is positioned for vertical reciprocating movement. The upper end of the plunger is provided with a knob or handle 8 and an expansible coil spring 9 is positioned on the plunger between the top of the frame 5 and the knob 8 to move the plunger upwardly.

A carriage designated generally at [0 is secured to the lower end of plunger 1, the carriage being of open frame construction open at its opposite sides, the open sides of the carriage coinciding with the open sides of the frame 5.

A substantially hook shaped support or seat I is suitably secured to the underside of the top of carriage H) and constructed of strap metal to form a seat for a roll of stamps l2 which is loosely supported on the seat or support H and with the free end of the roll extending downwardly under a feed roller l3 against which the stamp strip is held by a pressure roller l4 pivotally supported by the carriage l0 and provided with a spring l5 for holding the pressure roller against feed roller I3. The stamp strip is fed from the rollers I3 and I4 under a stationary guide plate IE to the front edge of a horizontal reciprocating cutter designated generally at H.

A gear I8 is rotatably mounted on one side of the carriage l0 engaging a gear I9 secured to one end of the shaft 20 for the feed roller I3. A ratchet 2| is secured to one side of gear l8 engaged by a row of teeth 22 on one edge of a vertical dog 23 which is pivoted as at 24 at its upper end to one side of the frame 5. The teeth 22 of the dog 23 are held in engagement with the ratchet 2| by means of a leaf spring 25 positioned longitudinally at the rear edge of the dog with its upper end secured to the stationary pivot 24 for the dog.

The teeth of the ratchet 2| and dog 23 are arranged to ride past each other during downward movement of the carriage I0 without rotating gear I8 and the return or upward movement of the carriage will cause a rotation of ratchet 2! by the teeth of the stationary dog 23 to thus rotate gear I8 and gear l9 and rotate feed roller 3 to feed the stamps in a step by step movement. The gear I8 is held against rotation during downward movement of the carriage by means of a dog 26 pivoted to one side of the carriage and engaging the teeth of gear I 8.

The cutter ll includes a V-shaped blade 21 sliding horizontally in a guide 28 suitably carried at the lower end of carriage I0, An arm 29 is pivoted to the rear portion of blade 2i and is inclined upwardly therefrom and pivoted at its upper end to an arm 30 secured in a horizontal position at the lower end of a shaft 3! rockably mounted in a vertical sleeve or housing 32 secured to one side of the carriage ID. The upper end of shaft 31 projects horizontally through an opening 33 in the adjacent side of carriage II] to provide a slide 34 positioned for vertical sliding movement in a guide channel 35 secured to the adjacent inner side wall of the frame 5. The lower end of guide channel 35 is inclined as shown at 36 in a direction to rock shaft'tl and swing arm 30 in a forward direction to move blade 2'! forwardly and to sever the stamp from the end of the stamp strip as the carriage It approaches its lowermost position.

A moistening roller 31 is journalled at the outer ends of a pair of arms 3.8 which are pivoted at their inner ends to the opposite ends of shaft 28 for feed roller l3. The arms 38 are positioned outwardly of the sides of the carriage it: toswingvertically by means of a gear 39 secured to one of the arms 38 engaging a vertical rack bar lit secured in a stationary position to the frame by means of a bracket 4! The vertical movement: of carriage if! swings arms. 38 and moistening roller 3:! downwardly under a curved presser plate E2 at the underside of cutter guide 28'. As the moistening roller 31- moves downwardly during downward movement of carriage ill the moistening roller engages the endmost stamp of the stamp strip and folds the same under the presser plate &2 and at the. same time moistens the adhesively coated underside of the stamp. and holds the stamp. against the bottom of presser plate 62 during the severing action by cutter blade 21.. The moistening roller 3'! swings rearwardly past presser'plate 42- as the stamp is pressedupon an envelope or the like, the presser plate 12 being of resilient material and free at one end' to flatten itself uponthe stamp by pressure exerted on the carriage by the plunger 1 and knob 8. During this action moistening roller 37' is swung upwardly against theunderside of a shield or stop 43' at the rear edge of frame 5.

During raisi-ng movement of carriage IS the moistening roller 37 is swung forwardly at the front of the frame 5 into engagement with an absorbent pad 66 held in a holder 45- suitably secured to the front edge of the frame 5; and saturated with a suitable liquid to be supplied to roller 31.

In View of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding, of the: device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred. embodiment of the invention, the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and. the scope of the appended claims.
